Three new coordination polymers, [Cd(mu(3)-PyBIE)(NO3)](n) (1), [Cd(mu(2)-HPyBIE)(2)(ClO4)(2)](n) (2) and {[Cd-1.5(mu(2)-HPyBIE)Cl-3]center dot 2H(2)O}(n) (3), were synthesized by the solvothermal reactions of a new benzimidazole derivative ligand, 1-(1-(pyridin-4-ylmethyl)-1H-benzoimidazol-2-yl)ethanol (HPyBIE). Crystal structure analysis showed that all the compounds were two-dimensional (2D) layer structures based on 1D helical secondary building units (SBUs). The helicity of 1D helical chain is dependent on the chiral conformation of HPyBIE ligand. Investigation of their structural diversity reveals that anions play an important role in the assembly procedure. Furthermore, the luminescence properties of compounds 1-3 were also studied.
